reference_wrapper、ref() 和cref() 现在禁止绑定到临时对象。 <random> 现在严格强制实施其编译时间的前置条件。 不同的 C++ 标准库类型特征共有的前置条件是“T 应为完整类型”。 虽然编译器更严格地强制执行此前提条件,但不会在所有情形中强制执行。 (由于 C++ 标准库前置条件违反了触发器未定义的行为,因此无...

According to the standard, the mutable specifier can be applied only to names of class data members, and can't be applied to names declared const or static, and can't be applied to reference members. For example, consider the following code: C++ Copy struct S { mutable int &r; }; ...

For the functions which return structs by value, ABI requires passing a special parameter which contains the address of memory where that returned struct should be placed. This parameter is implicit, users don't see it and can't provide any vector specification for it. Support for allowing such...
